BARREL.

Patented Oct. 22, 1907.

Application filed February 6| 1907- Serial No. 356,008.

To all "whom it may concern:

Be it known that I, FRANK E. Lower. a citizen of the United States, residing at E Erie and State of Pennsylvania, and useful Improvements in ll lowing is a specification.

This invention relates to barrels and tain improvements be hereinafter lul claims.

rie, in the county of have invented new arrels, oi which the l'olconsists in cerin the consttuction thereof as will ly described and pointed out in the The object of the invention. is to provide barrels preferably the ordinary ranged the form with l stave barrel, in which is arusual croze with a head of concave-convex hecoiwex side within the barrel the edges of the head resting in the croze and the head. inado elastic (:ircuinicrentially by corrugations extending from the extreme head is subjected to edge inwardly, so

that when the the pressure 01' the material within the barrel, the thrust incident to the arch shape is delivered almost entirely to the body of the barrel as dist nguished from being absorbed by the material forming the head as would be the case with a structure of concave-convex form, but without the corrugations. As a result of this construction, the edge oi the head more lirmly engages the body of the barrel at the croze so as to prevent its displacement in ordinary usage.

It is of concavo-convcx form with the convex side within the barrel.

This is provided with the corrugations (i which extend radially preferably from the center to the ed rugations make the edge 7 7. These corcomparatively elastic or extensible circumferentially so that when weight is put on the head, the thrust incident to the arch shape of the head is delivered almost entirely the barrel along the croze.

to the body of r l l l I prefer to have the surface 4 coincident with the edge of the head that is to say the surface 4 is so formed with relation to the convolutions of the edge of the head as to contact all points along the edge as distinguished from a surface or shape of croze that will contact the apexes or bends only of the convolutions, so that the corrugated edge will form a lit throughout the length of the edge. The thrust incident to the pressure on the arch shaped head will form more or less of an indeuture in the comparatively soft material in which the croze is formed so that any slight unevenness there may be in the surface does not prevent the forming of a tight joint. The thrust, therefore, incident to the elastic edge and arch shaped head not only more i irmly engages the edge of the croze so as to prevent displacement, but also insures a more perfect closure. This is particularly desirable where the barrel is to be used [or liquids or line materials.

What I claim as new is:

1. In a barrel the combination with the body portion of the barrel having a eroze formed therein of a barrel head of concave-convex shape with the convex side within the barrel and having corrugations extendingfrom the extreme edge of the head inwardly, the edge of the head resting in the croze.

2. In a barrel the combination with a body portion of the barrel having a croze formed therein of a barrel head of concave-convex shape with the convex side within the barrel and having corrugations extending from the extreme L( go of the head inwardly, the edge of the head resting in the croze, the surface of the croze engaged by the head being coincident with the edge of the head.

.3. I11 a barrel the combination with the body portion of the barrel formed of comparatively soft material and having a croze formed therein; of a barrel head formed of comparatively hard material and or concavo-convex shape with the convex side within the barrel and having corrugations extending .from the extreme edge of the head inwardly, the edge of the head resting in the croze and with the surface of the croze engaged by the head coincident with the edge of the head.

4. In a barrel the combination with the body portion of the barrel having a croze formed therein; of a head of conc:.1vo-convex shape with the convex side within the barrel and having corrugations extending from the extreme edge of the head inwardly, the edge of the head resting in the crozc, the head having a greater normal diameter than the body of the barrel at the outside edge of the croze.

In testimony whereof I hax e hereunto set my hand in the presence of two subscribing witnesses.
